A balancing drum in accordance with claim 1 wherein, all the sides of the said balancing drum are closed and sealed which only allows the balancing fluid entrance into the balancing cells through slots as a doughnut shape on the side of the balancing drum which is not used for mounting to the main drum or rotor. 4. A fluid injecting system in accordance with claim 1 wherein, at least one balancing fluid injector system is used for each of the balancing drums, at least one fluid flow control valve is used for each injector system on a pipe with a nozzle at the injecting end in order to accelerate the fluid flow rate, said injector nozzle is fixed facing to the opened side of the balancing drum, the injector control valve (s) in the balancing system are precisely controlled in such a way that the required amount of balancing fluid is injected into the required position of the balancing drum during balancing operation. 5. A fluid injecting system in accordance with claim 1 wherein, separate injector systems are used for each balancing cell and also for each of the balancing drums, each said injector system means a narrow liquid canal in a ring form as its rotating axis is the same with drum rotating axis and only the sides of the ring facing rotation axis are opened, each of the said liquid canal is connected to one balancing cell by a proper connection system injected liquid in the canal, pass through said connection system to enter the balancing cell by centrifugal force effect, at least one injection control valve placed on the injecting system to control fluid flow injected in the rotating liquid canal. 6. A machine in accordance with claim 1 wherein, the rotational drum housing structure is flexibly mounted to the main rigid body structure, the position, magnitude and direction of the imbalance vectors are calculated by purpose built controllers by using the imbalance signals sensed by the fitted sensors, it is a high speed centrifugal spinning machine, used for extracting fluids from the liquid absorbent goods, in which the sensed imbalance vectors are processed in a suitably programmed controller unit in order to calculate precisely the amount of counter-weight to be injected into the correct balancing cell of the balancing drum or drums to balance the system which rotates together. 7. A machine in accordance with claim 6 wherein, it can also be considered as a washing machine used for textile and garment washing. 8. A machine in accordance with claim 6 wherein, it can also be considered as a dying machine in textile garment dyeing. 9. A machine in accordance with claim 6 wherein, it can also be considered as a machine which can be used as a stone-wash machine. 10. A machine in accordance with claim 6 wherein, the rotational drum housing system flexibly supported by gas pressurised rubber bellows. 11. A machine in accordance with claim 6 wherein, the rotational drum housing system flexibly supported by rubber or similar flexible material blocks, 12. A machine in accordance with claim 6 wherein, the rotational drum housing system flexibly supported by suspension springs either hang by springs or placed on a platform supported by springs. 13. A machine in accordance with claim 6 wherein, the rotational drum housing system flexibly supported by flexible or semiflexible metal, plastic or any similar synthetic coupling or fixing material. 14. A machine in accordance with claim 6 wherein, the control system takes care of time delay characteristics of the system to activate the required number of injector valves for counter weighing, the control system continuously monitors the accepted and applying values of the system time delays, the system also use a reference point for said controlling on the drum assembly, said reference point is provided from a notch via a switch or sensor or an encoder connected to the rotating shaft of the drum, the balance control system checks and measures the angle between the position of the imbalance vector and position of the reference point on the drum system, before starting the balancing operation, the control system continuously monitors the said pre-detected angle during balancing operation, the control system change the time delay constant used in calculations if any deviation is recognised in the value of the said pre-detected angle. 15. An extraction machine in accordance with claim 6 wherein, rotation axis of the drum is horizontal, the balancing drum is mounted on the main rotating drum with the same rotational axis, separator plates of the balancing cells placed in the direction of the rotational axis as each cell having equal volume, balancing drum/drums are placed in the drum housing so water can be chosen as balancing fluid. 16. A balancing drum in accordance with claim 15 wherein, the number of the balancing cells equal to the number of ribs used in the main rotating drum and they are placed to connect each rib to the centre of the corresponding balance cell, said balancing cells share same volume with the corresponding ribs as the balancing fluid injected in that particular cell can pass through into the corresponding rib and vice-versa but sealed properly in order to prevent any leak from the ribs. 17.
